To all whom/.zit may concern:

common torotary engines.

-Be it known that I, PAUL J. DE BRYN Kors, a citizen of the United States, residing at Wake, in the county of Middlesex and State of Virginia, haveinvented a new and useful Rotary Enginefof which the following is aspeciiication. y

My invention relates to rotary engines in which a pressure fluid, as steam, is used to drive or rotate the piston and the objects of my improvements are,first, to provide a compact and durable construction; second, to -make the operating parts of simple construction; third,.to have the fluid-pressure-supply valves operate automatically without any lever or rod connections; fourth, to facilitate. the compounding of the ressure fluid; fifth, to enable-the reversing o the engine, and other objects to become apparent from the description to follow.

By the use of my invention I aim to` over come many of the objectionable features All lever, cam, or rod connectionswith relation to thel supply-valves are dispensed with, which obviates the possibility of these parts getting out of order or refusing to properly work during high speed. A very simple and inexpensive means is provided for compounding the pressure fluid, and the valves for. admitting the pressure ,fluid into the piston-chamber serve also as the abutments in the piston-chamber, thus reducing the number of parts to a minimum.

The engine, generally speaking, consists of three parts-the revolving piston and the two-piece framev inclosing. the same. The valves ory controlling parts for the pressure fluid are arranged to move in the` frame and in and .out of arcuatel grooves provided on the sidesl of vthe wheel-like piston. These controlling parts I'term the .valves,H which also serve as the abutments for the fluid-pres- ;sure whenforcing the piston around and are of a novel construction. They are so made that by giving them a one-quarter rotation -in either .direction it will cause the piston to rotate in an opposite direction.

I have illustrated an engine embodying .my invention on the accompanying three sheets of drawings, forming a part of this specification, in which- Figure 1 is a side elevation. Fig..` 2 is a section on line 2 2 of Fig. 1, partly in elevation. y Fig. 3 is aside elevation of the piston detached. Fig. -41is a section on line 4 4 of Fig. 3. Fig. 5 is asection on line 5 5 of Fig. 3. Fig. 6 is a section on line 6 6 of Fig. 3. Fig. 7 is a section on line 7 7 ofFig. 2. Fig. 8 1s a similar view showing the valve in another position. Fig. 9 isa section on line 9 9 of Fig. 7,'

and Fig. 10 is a section on line 10 10 of Fig. 9.

Similar reference characters refer to simii lar parts throughout the several views.

'Ihe frame 1() may be of any desired form, but I prefer to make it of two counterparts `11 and 12, secured together bybolts 13 and mounted on a base 14. The frame is provided with brackets 15, surmounted by bearings for the shaft 16, on which is secured the wheel-like piston 17, the rim of which is slidinglyfitted between the frame parts 11 and 12.

Both sides of the rim of the piston 1 7 are provided with similarly formed arcuate grooves, those on one side being on one half of the piston and those on the other side be-y ing on the other half of the piston, so as to keep the piston in perfect balance. The grooves 18 and 19 (see Figs. 3 and 4) are smaller in area and closer tothe shaft 16 than the grooves 20 and 21. i This is to provide for the expansion of the pressure fluid, which is first admitted to the grooves 18 and 19,'and after exhausting from these is admitted into the larger grooves 20and 21. To accomplish this, I provide the sliding valves 22 and 23 for the grooves 18 and 19, respectively, and the similar valves 24 and 25 for the grooves 20 and 21, respectively. The high-pressure-fluid pipes 26 lead to the valves 22 and 23, while the exhaust-ports 27 lead Y from the grooves 18 and 19.to the valves 24 and 25. In this one respect only is there any difference in the valves 22, 23, 24, and 25 as to their construction, o eration, and con-` nection, and I will there ore describe only one of said valves in detail, which will lsuffice for a description of all four.

Referring to Figs. 7 to 10, valve 24 is made to fit snugly in .a round bore 28 in the extension 29 provided on the frame 10 and extending out laterally therefrom directly yover the groove 20in the piston 17. To constantly hold the one end of the valve 24 againstthe piston 17 so thatit will rest snugly against thebottom of the groove 20 at the proper time, an enlargement 30 is provided on the other end of the valvewhich fits in the enlarged bore 31 and npressure fiuid is admitted through the passage 32 from the inlet 27,to constantly press against the end of the valve,

.there -being a vent 33 in the extension 29-be- IOO IIO

tions the valve may be in.

low the enlargement 30 leading to the outside atmosphere.

' The end of the valve 24 adjacent to the piston 17 is provided with two diametrically oppositely arranged longitudinal grooves 34, extending from near the extreme end of the valve back a distance equal to the greatest de th of the groove 20, where they merge into t e broader grooves 35. Each groove 34 extends slightly less than one-quarter way around the valve 24, so that a perfect abutmentv will be formed by the valve 24 in the groove 20, no matter which of its two posi- (See Fig. 10.) Each groove 35 extends circumferentially slightly less than one-half way around the valve, longitudinally just beyond the inletport 27, and necessarily one is diametrically opposite the other. rlhe reason for making two grooves 34 and two grooves 35 is to enable the reversing of the engine, which is done by rotating all the valves one-quarter way.

It will be seen that when the valve is in the position shown in Fig. 7 the pressure Huid will enter groove 35 from port 27, pass through groove 34 and enter the groove 20 in the piston 17, so as to rotate the piston in the direction indicated by the arrow in Fig. 10, and if the valve is placed in the reverse position, as seen in Fig. 8, the pressure fluid will enter the groove 20 in piston 17, so as to rotate the piston in a direction reverse to that indicated by the arrow in Fig. 10.

Any convenient means may be provided to simultaneously rotate all four valves a onequarter revolution. I have shown one, which consists of providing each valve with a concentric square hole 36, into which is slidingly tted the square end of a shaft 37, which extends out through a stuffing-box 38 and has secured to its outer end a crank-arm 39. As seen in Figs. 1 and 2, the crank-arms 39 on either side of the engine are connected by links 40, and the upper ends of these links are connected by other links 41 to across-bar 42 of a hand-lever 43, which is pivoted to the frame 10 at 44. To rotate the valves, the hand-lever 43 is moved down or up, as the case may be.

The grooves 18, 19, 20, and 21 extend circumferentially one-half way around on the piston and each of them has its bottom inclined in either direction to form the approaches shown in Figs. 5 and 6.

In operation, referring to the side shown in Fig. 1, the pressure lluid enters at 26, passes througl valve 22 and into the groove 18, forcing the piston 17 around in the direction indicated by the arrow in Fig. 1. When the rear end of the groove 18 reaches the valve 22, the front end of the groove 20 is at valve 24, (in which position it is shown by dotted lines at Fig. 1,) the flow of pressure fluid at valve 22 is shut off, and the expanding pressure of the fluid in groove 18 is starting to pass4 through port 27 and valve 24 into groove 20, the front end of which is now at valve 24, thus assisting in the rotation of the piston 17. As the piston continues to revolve the valve 24 enters the groove 20 and the pressure fluid in the groove 2O back of valve 24 is allowed to exhaust to the atmosphere through port 45 d uring the time that the pressure fluid from groove 18 is passing through port 27 and valve 24 into groove 20 in front of valve 24. As the piston 17 revolves still further and the front end of groove 18 reaches valve 22 again, said valve enters said groove and the fluid rem ainingin groove 18 after passing port 27 is allowed to exhaust into the atmosphere through valve 22 and port 46.

The grooves and their respective valves on either side of the piston are so arranged with relation to each other that when the pressure fluid at valve 22'is about to be shut ofi the pressure fluid at valve 23 is turned on, so that the engine has no dead-center Having thus fully described my invention, what l claim as new, and desire to secure by Letters Patent of the United States, is-
